Description

Technical Field

[0001] The utility model relates to the technical field of adhesive filtration, and more specifically to a multi-layer filtration device for adhesives. Background Art

[0002] During the production process of adhesives, the filtration device is an important component. Its main function is to filter raw materials or intermediate products to remove impurities and ensure the purity and quality of the products. The filtration device for adhesive production usually adopts a hierarchical filtration method. First, it is preliminarily filtered through a coarse filter cover, and then secondary filtered through a fine filter cover to ensure the filtration effect.

[0003] For example, in a water-based adhesive hierarchical filtration device with the publication number CN214415807U, it is proposed that the current water-based adhesive filtration devices on the market often adopt one-time filtration. Not only are the impurities inside not filtered cleanly, but also precipitation is likely to form inside, which is not conducive to subsequent cleaning. First, it is preliminarily filtered through a coarse filter cover, and then re-filtered through a fine filter cover. By using such a two-stage hierarchical filtration method, the filtration is cleaner; through the use of components such as a motor, a coarse filter scraper, and a fine filter scraper, the motor drives the coarse filter cover to rotate. The rotation of the coarse filter cover drives the fine filter scraper to rotate inside the fine filter cover, so as to scrape off the precipitation inside the fine filter cover. At the same time, the coarse filter cover rotates outside the coarse filter scraper, and the coarse filter scraper scrapes off the precipitation inside the rotating coarse filter cover.

[0004] However, in the above device, the fine filter cover is located between the coarse filter cover and the fixed cover. When the filter cover needs to be cleaned, it is not convenient to clean the fine filter cover, resulting in inconvenient subsequent cleaning. Summary of the Utility Model

A second bevel gear meshing with the surface of the first bevel gear is fixedly connected to the surface of the hollow tube. The connecting tube is connected to an external delivery pump through a pipeline.

[0008] Further, a T-shaped mounting opening is formed in the upper surface of the concave mounting plate. The surface of the mounting frame abuts against the inner wall of the mounting opening. The shape of the mounting frame is T-shaped. A T-shaped groove is formed in the side surface of the mounting frame. A sliding block is slidably connected to the inner wall of the T-shaped groove. A connecting spring is fixedly connected between the opposite surfaces of the sliding block and the T-shaped groove. A positioning block is fixedly connected to the surface of the sliding block away from the connecting spring. The upper surface of the positioning block is arc-shaped. An operating block is fixedly connected to the lower surface of the positioning block. An operating opening communicating with the inside of the T-shaped groove is formed in the lower surface of the mounting frame. The surface of the operating block abuts against the inner wall of the operating opening. A positioning groove adapted to the positioning block is formed in the inner wall of the T-shaped mounting opening.

The filter meshes on the concave mounting plates can filter the adhesive, and the upper and lower multi-layer filter meshes can perform multi-layer filtering. During the filtering process, the driving motor is started. The driving motor drives the hollow tube to rotate through the first bevel gear and the second bevel gear. The hollow tube drives the scraper to rotate through the shunt pipe, which can push the impurities above the filter mesh to avoid clogging the filtering holes of the filter mesh and ensure the filtering effect. After the filtering is completed, the cleaning liquid is conveyed into the connecting pipe through an external delivery pump. The cleaning liquid flows through the hollow tube and the shunt pipe to the nozzle and sprays out. As the shunt pipe rotates, the nozzle can cover and clean the filter mesh, thus facilitating the cleaning of the device.

At this time, the upper arc surface of the positioning block is automatically received under force, and the connecting spring is compressed. When the positioning block moves to the positioning groove, the elastic force of the connecting spring pushes the positioning block into the positioning groove to complete the fixation of the filter mesh.
